Renault 11 mechanical consultation

Hello friends, I have a query about my renault 11ts, it turns out that when I stop it, it begins to smell a lot of naphtha smell, as the engine still stopped, it will continue to enter the carburetor fuel, sometimes it has even been difficult to start it, I do not have very often very often but it has happened, I am not very expert in mechanics but I give a morning to repair it.
It is more, many meconics have put hand to me but they left me worse, much of the problems solve them, after the manual from here, but with this of the smell of the cobuel

Look in carbureted vehicles, a slight smell is normal, already when the spark is short, but being with a mechanical pump is secrer delivering fuel until the engine stops, the other failure you can have is that the carburetor tank is discharged due to problems of the float or needle, I think I.

And Nadamas to complete deverias check all your manglasses if there is no small leak, even a small one produces a lot Smell in carburers is normal.

I share the same opinion with the two previous friends but you should check the vent of the fuel pond since, like these carbureted and mechanical pump models, in some cases the pressure within the tank makes the benzine continue to flow through the circuit until entering the carburetor, but anyway all the data is valid tests with all this greetings.

Hi Vicadri,
in addition to the previous tips, in that system the carburetor float acts a needle valve that is the one that opens or closes the fuel passage according to the position of the float, sometimes it is locked in the place where the seat is housed or is damaged and does not regulate the step. Verify that. Luck.
